WatchMonCORE

Introducing the next generation of WatchMon supervisors. This revamps takes the lessons we have learnt from WM4 and builds on this proven platform with a few new features.

WatchMonCORE will be the core building block and additional components will link to this supervisor in the future.

Overview

Versatile Supervisor works with both distributed and centralised cell monitors
User-configurable parameters and control logic
Configurable 30vdc 5Amax relay (i.e. remote circuit breaker trip, contactor or fan)
Additional inputs/outputs via Expansion Board purchased separately
Compatible with all Expansion Board (series 1, 2, or 3)
Clock with a backup battery
Data logging of key metrics for 10 years
Firmware upgrades via USB
4-stage display of State of Charge (SoC%)
External ambient temperature sensor
Easy to use pluggable screw-terminal connectors
Link to Shuntmon with 500A or 1000A power rating

Remote Communication

WiFi connectivity (normal, disabled, or read-only)
CAN bus Opto-Insulated to remote charger/inverter equipment
Future feature to connect to the cloud portal via MQTT (secure link).

Power Input

Built-in 8v to 30v DC-DC supply
With WiFi-enabled consumes ~1.7W (Typical 48v battery budget 1Ah/day)

When powering the WatchMonCORE (version 4.5) with a supply above 30Vdc (i.e. 48V battery pack voltage), always connect to an isolated DC-DC (ideally 24Vdc) to ensure a robust, long-term, and reliable product.

Optional Extras that can be Purchased:

TestMon - checks and confirms your wiring
Expansion Board
500A or 1000A Shunt Monitor
TestMon16
Extra Support - * Email fair use is included free but if you need more help and advanced technical assistance, you can buy upfront or later on an as-needed basis via Zoom or similar.

Optional Expansion Board (Series 3) details

3 x Mechanical 30Vdc 5A relay outputs
3 x Solid state relay SSR 65vdc 5Amax isolated modules outputs (1A cont.)
2 x Isolated inputs 5-65vdc sensor channel
2 x ADC 0-5vdc (future development option)
1 x RS485 Serial port (future development option)
1 x Remote Addressable LED (future development option)
Compatible with all supervisors

Mounting a Fan

CellMate-K9 has been designed to allow a 60mm Fan to be mounted to enhance balancing performance if the customer desires.

*Fan and standoffs are not supplied.

M3 screws to mount Hex standoffs to the CellMate-K9
Standoffs should be 30mm in height in order to clear the heat sink.
Fan hole centres are 60mm apart.
Fan power can be triggered by the logic of the WatchMon CORE
Adopt one of the Relay/SSR to switch the fan power.
Fan selection is a customer choice, Voltage (12,24,48,5V) etc.
The fan is not to be powered from the onboard 5V DC-DC of the WatchMon CORE
